The sun was setting behind the tall buildings of Tokyo, casting long shadows over the quiet streets. You and Chifuyu Matsuno walked side by side, the sounds of the city humming in the background, but the two of you were comfortable in the silence.

Chifuyu had been unusually quiet today, his usual playful demeanor replaced by something more introspective. You stole a glance at him, noticing the way he occasionally ran a hand through his messy hair, his eyes distant, as if lost in thought.

"Everything okay?" you asked, breaking the silence with your soft voice.

He looked at you, his expression softening slightly. "Yeah, just... thinking."

"About what?" you prodded gently, not wanting to push too hard but sensing that something was weighing on him.

Chifuyu hesitated for a moment, his lips curling into a small smile, though it didn’t quite reach his eyes. "Nothing important. Just work stuff, you know?"
